The Small B/W Wall Clock Camera (lower left, $276) has a black-and-white camera hidden inside, while the Air Freshener 3G Camera (lower middle, $720) has a color camera inside plus a SIM card that lets you watch the live video feed on a 3G phone. The Power Strip Hidden Audio Monitoring Device (upper left, $1209) is also rigged with a SIM card and a microphone, so you can dial in and listen to conversations. For $100 more, you can get a version that calls you when it detects voices in the room.
